Abstract

A rotary oxygenization ejector comprises a pressure water pipe, an air tube and an ejector, and is characterized in that a nozzle communicated with the pressure water pipe is provided in the ejector; the nozzle is of conical shape, and is of a same concentric line with a throat which is movably fit to between the nozzle and the ejector. An air chamber is formed between the nozzle and the throat; the throat is a straight tube. Air tubes are provided on one side or both sides of the top of the ejector. The lower end of the throat is permanently with rotary feed pipes; each of the feed pipes extends downwards, and bends to form a level segment. A level or downwards inclined gas-liquid spout is provided at the end of the feed pipe. The gas-liquid spout is equispaced on circumference around the axial line of the ejector in the direction, which is tangential to the circumference and contrary to the rotation direction of the rotary feed pipe. The utility model has the advantages of low cost, low dissipation of energy, easiness to be maintained. The utility model jets in a rotary manner through a plurality of gas-liquid spouts, can not only significantly increase service area, but also fully convert the energy provided by pressure water so that air is cut into microscopic bubbles which will enter the basin; accordingly, bubbles are prevented from gathering again, and utility model meets the requirement for microbes to dissolve oxygen.

Description

Oxygenation rotating jet device

Technical field

The utility model relates to a kind of equipment of disposing of sewage, and particularly a kind of is the oxygenation rotating jet device that is used for sewage disposal.

Background technology

Traditional wastewater is administered the objectionable impurities in the process using aerobic degradation sewage, and ejector is as providing a kind of equipment of oxygen to be widely used to microorganism.Because traditional ejector has only the gas-liquid spout of a fixed and nozzle coaxial line, active area is similar to a point, makes service area little, and oxygen transfer rate is low, causes the energy consumption height.Replaced by the oxygen replenishing equipment of other form.

Summary of the invention

Technical problem to be solved in the utility model is, adopt a plurality of gas-liquid spouts of rotation, the mixed solution of ejection forms the anchor ring of certain width, make service area be extended to the several times of traditional ejector, distance between rotating jet device and the gas-liquid spout is near, can guarantee by the air filled cavity minimum of ejector cutting, be beneficial to combining of oxygen molecule and microorganism, reach the purpose of waste water treatment through the ejection of gas-liquid spout.

The technical solution adopted in the utility model is such, promptly a kind of oxygenation rotating jet device, and it comprises pressure water pipeline, blast main, ejector; It is characterized in that: in the housing on ejector top, be provided with the nozzle that communicates with pressure water pipe, this nozzle is tapered to be the trunnion coaxial line that is connected movingly downwards with between the ejector, keep certain distance to form a wind box between nozzle and trunnion, described trunnion is a straight tube, one or both sides on the top of the housing of ejector are provided with the blast main that communicates with wind box, be connected with the revolving ozone distribution pipe in the trunnion lower end, each gas distribution pipe extends downwards and bends to horizontal section, its tail end be level or be tilted under the gas-liquid spout, the gas-liquid spout is around ejector axis circumference uniform distribution, and direction is that circumference is tangential and opposite with revolving ozone distribution pipe rotation direction.

Description of drawings

Description of drawings of the present utility model is as follows:

Fig. 1 is a structural representation of the present utility model;

Fig. 2 is that the A of Fig. 1 is to view;

Fig. 3 is a user mode reference drawing of the present utility model.

Among the figure: 1. pressure water pipeline; 2. ejector; 3. blast main; 4. nozzle; 5. wind box; 6. trunnion; 7. revolving ozone distribution pipe; 8. gas-liquid spout; 9. thrust groove; 10. thrust ring; 11. end cap; 12. resistance baffle plate.

Embodiment

The utility model is described in further detail below in conjunction with drawings and Examples:

See accompanying drawing 1 or 2, in the embodiment that accompanying drawing provides, oxygenation rotating jet device comprises pressure water pipeline 1, blast main 3, ejector 2; Wherein: in the housing on ejector 2 tops, be provided with the nozzle 4 that communicates with pressure water pipe 1, this nozzle is tapered to be trunnion 6 coaxial lines that are connected movingly downwards with between the ejector 2, keep certain distance to form a wind box 5 between nozzle 4 and trunnion, described trunnion 6 is a straight tube, one or both sides on the top of the housing of ejector 2 are provided with the blast main 3 that communicates with wind box, be connected with revolving ozone distribution pipe 7 in the trunnion lower end, each gas distribution pipe extends downwards and bends to horizontal section, its tail end be level or be tilted under gas-liquid spout 8, gas-liquid spout 8 is around ejector axis circumference uniform distribution, and direction is that circumference is tangential and opposite with revolving ozone distribution pipe rotation direction.

Outwards open gradually radial branching is 2-4 to described revolving ozone distribution pipe 7 in the trunnion bottom.

See accompanying drawing 1, be connected with thrust ring 10 in the middle of trunnion 6, thrust ring is positioned at the ring groove 9 of the lower housing portion of ejector 2, and the housing bottom of ejector is connected with end cap 11.Realize being connected movingly between trunnion and the ejector 2.The effect of described thrust ring is: make trunnion 6 can only rotate and can not move between the housing of ejector and end cap 11.

See accompanying drawing 1 or 2, vertical or tilt to be connected with resistance baffle plate 12 at the horizontal section of revolving ozone distribution pipe 7.Stir service area to increase, the velocity of rotation of the resistance limits revolving ozone distribution pipe 7 that resistance baffle plate 12 produces.

See accompanying drawing 3, the working process of the rotating jet device that the utility model relates to, in being housed, the pond of sewage vertically fixedly mounts the pressure water pipeline, the ejector housing links to each other with the water supply line of vertical fixing installation in the pond, whole rotating jet device is positioned at below the horizontal plane, near the gas-liquid spout is positioned at the bottom of the pond, the pressure water that the pressure water pipeline is carried is jet-like through nozzle and sprays into and produce wall attachment effect (negative pressure) in the trunnion, air is sucked wind box by blast main, the air that enters in the trunnion is mixed by water, cutting, through the gas-liquid spout ejection of revolving ozone distribution pipe end, airborne oxygen molecule is absorbed by the microorganism in the water, and microorganism is realized the degraded to objectionable impurities in the sewage.

The reactive force that above-mentioned gas-liquid spout 8 produces when spraying promotes revolving ozone distribution pipe 7 by direction rotation shown in Figure 2, and pool bottom sludge is played certain stirring action.

The utility model has carried out abundant conversion with the energy that pressure water provides, and has increased service area, and air promptly enters in the pond after being cut into microbubble by ejector, has effectively prevented the cohesion again of bubble, has better met microorganism to the dissolved oxygen requirement.

In sum, the utility model is compared with other oxygen replenishing equipment, have that equipment investment is little, energy consumption is low, The advantage of being convenient to or avoiding keeping in repair.
